# Alpha memo: resveratrol exercise training translation boundary
**One-sentence alpha:** Resveratrol plus exercise may protect against intestinal damage in mice yet may blunt training-induced cardiovascular gains in aged men, suggesting the interaction is bounded by tissue and population.
**Receipt 1:** Resveratrol attenuated high intensity exercise training-induced inflammation and ferroptosis via Nrf2/FTH1/GPX4 pathway in intestine of mice — in mice, 15 mg/kg/day resveratrol alongside 28 days of swimming reduced inflammatory factors and intestinal permeability markers associated with high-intensity exercise-induced gastrointestinal syndrome.
**Receipt 2:** Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men — in 27 physically inactive men aged 65 ± 1 years randomized to 250 mg/day trans-resveratrol or placebo with 8 weeks of high-intensity training, the resveratrol group showed a smaller training-induced rise in maximal oxygen uptake than placebo, and MAP did not improve as in placebo.
**Why this is surprising:** Receipt 1 made plausible a broadly beneficial resveratrol-plus-exercise signal (organ protection in a rodent high-intensity model), and Receipt 2 updates that by showing the same anchor can reverse direction on a human cardiovascular endpoint in older men.
**Caveats/falsifiers:**
- Receipt 1 uses mice at 15 mg/kg/day for 28 days measuring intestinal inflammation/ferroptosis markers, while Receipt 2 uses aged men at 250 mg/day for 8 weeks measuring VO2max and MAP; the species, dose, route, duration, tissue, and baseline age all differ, so any single-moderator explanation (e.g., age or dose) is tentative and confounded.
- Sample size is small in Receipt 2 (n=13–14 per arm); a decisive falsifier would be a randomized trial in aged men at matched-equivalent doses that restores a training-only VO2max gain when resveratrol is added.
